Definitions
- the present invention relates, in general, to fluid quick connectors which couple fluid carrying components.
- Snap-fit or quick connectors are employed in a wide range of applications, particularly, for joining fluid carrying conduits in automotive and industrial application.
- the retainer In a typical quick connector with an axially displaceable retainer, the retainer is fixedly mounted within a bore in a housing of a connector component or element.
- the retainer has a plurality of radially and angularly extending legs which extend inwardly toward the axial center line of the bore in the housing.
- a tube or fitting to be sealingly mounted in the bore in the housing includes a radially upset portion or flange which abuts an inner peripheral surface of the retainer legs.
- Seal and spacer members as well as a bearing or top hat are typically mounted in the bore ahead of the retainer to form a seal between the housing and the fitting when the fitting is lockingly engaged with the retainer legs.
- Radially displaceable retainers in which the retainer is radially displaceable through aligned bores or apertures formed transversely to the main through bore in the housing are also known.
- the radially displaceable retainer is typically provided with a pair of depending legs which are sized and positioned to slip behind the radially upset portion or flange on the fitting only when the fitting or conduit is fully seated in the bore in the connector. This ensures a positive locking engagement of the conduit with the connector as well as providing an indication that the conduit is fully seated since the radially displaceable retainer can be fully inserted into the connector only when the conduit has been fully inserted into the bore in the connector.
- the housing of a fluid connector typically includes an elongated stem having one or more annular barbs spaced from a first end.
- the barbs provide secure engagement with a hose or conduit which is forced over the barbs to connect the housing with one end of the conduit.
- the open end of the axial through bore in the connector portion of a fluid connector designed with an axially displaceable retainer or the transverse bores in a connector designed to receive a radially displaceable retainer are fixed in one circumferential position depending upon the position of the tubing and the connector when the conduit and the connector are joined together.
- this could limit accessibility to and make it difficult to insert the retainer into the connector, particularly in the case of a radial retainer.

- the first housing has an annular recess spaced from a first end and opening to the through bore to define a radially inturned lip at the first end.
- a plurality of separate latch fingers extending axially from one end of the second housing each having a radially outward extending projection defining an adjacent recess.
- the lip of the first housing is engagable in the recess on the second housing to axially connect the first and second housings to each other while permitting rotational displacement of the first and second housings relative to each other.
- a collar extends axially from the projection on each latch finger. The collar retains the seal means in the first housing when the first and second housing are joined together.
- the collar is formed as an axial extension of a plurality of discrete, bendable latch fingers.
- a radially outward extending projection is formed on each latch finger.
- Each projection defines an arcuate recess with an adjacent spaced portion of the second housing for rotatably receiving the lip on the first housing.
- annular recess is formed in the second housing and opening to the transverse bore in the second housing.
- the annular recess receives an enlarged flange on the second conduit when the retainer is moved to the latch position in the second housing.

Abstract
Description
- The present invention relates, in general, to fluid quick connectors which couple fluid carrying components.
- Snap-fit or quick connectors are employed in a wide range of applications, particularly, for joining fluid carrying conduits in automotive and industrial application. In a typical quick connector with an axially displaceable retainer, the retainer is fixedly mounted within a bore in a housing of a connector component or element. The retainer has a plurality of radially and angularly extending legs which extend inwardly toward the axial center line of the bore in the housing. A tube or fitting to be sealingly mounted in the bore in the housing includes a radially upset portion or flange which abuts an inner peripheral surface of the retainer legs. Seal and spacer members as well as a bearing or top hat are typically mounted in the bore ahead of the retainer to form a seal between the housing and the fitting when the fitting is lockingly engaged with the retainer legs.
- Radially displaceable retainers in which the retainer is radially displaceable through aligned bores or apertures formed transversely to the main through bore in the housing are also known. The radially displaceable retainer is typically provided with a pair of depending legs which are sized and positioned to slip behind the radially upset portion or flange on the fitting only when the fitting or conduit is fully seated in the bore in the connector. This ensures a positive locking engagement of the conduit with the connector as well as providing an indication that the conduit is fully seated since the radially displaceable retainer can be fully inserted into the connector only when the conduit has been fully inserted into the bore in the connector.
- Regardless of the type of retainer, the housing of a fluid connector typically includes an elongated stem having one or more annular barbs spaced from a first end. The barbs provide secure engagement with a hose or conduit which is forced over the barbs to connect the housing with one end of the conduit.
- Due to the secure engagement between the conduit and the housing, the open end of the axial through bore in the connector portion of a fluid connector designed with an axially displaceable retainer or the transverse bores in a connector designed to receive a radially displaceable retainer are fixed in one circumferential position depending upon the position of the tubing and the connector when the conduit and the connector are joined together. In certain applications, this could limit accessibility to and make it difficult to insert the retainer into the connector, particularly in the case of a radial retainer. Interference with surrounding components frequently makes access to the quick connector for both locking or unlocking operations difficult, if not impossible.
- To address these problems, two part fluid quick connectors which are easily rotatable over 360° to facilitate insertion or removal of the retainer into or out of the quick connector have been devised. In such quick connectors, the quick connector housing, typically of one piece construction, is replaced with two engagable portions, one attachable to or mountable on a fluid component, such as a tube or conduit, and the other receiving a second conduit or endform as well as receiving the retainer for locking the first component and the endform together.
- Thus, it would be desirable to provide a rotatable two piece quick connector which provides the known advantages of two part rotatable quick connectors with two part fluid quick connector housings.
- The present invention is a fluid quick connector for joining first and second conduits in fluid flow communication. The quick connector includes seal means mounted in the through bore of a first housing for sealing engagement with a second conduit, a second housing having a bore for receiving the second conduit therethrough, and a retainer mountable in the second housing for lockingly coupling the second conduit to the second housing. The first housing has an annular recess spaced from a first end and opening to the through bore to define a radially inturned lip at the first end. A plurality of separate latch fingers extending axially from one end of the second housing each having a radially outward extending projection defining an adjacent recess. The lip of the first housing is engagable in the recess on the second housing to axially connect the first and second housings to each other while permitting rotational displacement of the first and second housings relative to each other. A collar extends axially from the projection on each latch finger. The collar retains the seal means in the first housing when the first and second housing are joined together.
- One aspect, the collar is formed as an axial extension of a plurality of discrete, bendable latch fingers. A radially outward extending projection is formed on each latch finger. Each projection defines an arcuate recess with an adjacent spaced portion of the second housing for rotatably receiving the lip on the first housing.
- In another aspect, an annular recess is formed in the second housing and opening to the transverse bore in the second housing. The annular recess receives an enlarged flange on the second conduit when the retainer is moved to the latch position in the second housing.
- A rotatable two part fluid quick connector of the present invention provides all the advantages of a fluid quick connector with a latchable retainer while at the same time allowing the two quick connector housings to rotate relative to each other to simplify installation and to be used in many diverse applications having different space requirements.
- The various features, advantages and other uses of the present invention will become more apparent by referring to the following detailed description and drawing in which:
